To all whom it may concern:

Be it known that L'Fnami L. Sessions, a

.citizen ofthe United States, residingat- Columbus,in the county of Franklin' and State of Ohio, have invented certain new 'and ilse'- ul Improvements in Separators for Storage- Battery Plates, of which the fol-lowing` is a specification;referencebeing had therein to the Vacconipanying drawing. t

Thisl invention relates to separators for storage battery plates'. The object of the invention is to provide a separator which will more 4perfect-ly insulate ,the plates onev from another and, at the saine time," allowl perfect` freedom 'of communication to per-init the movement Vof the ions from one plate tothe other.

Separator's embodying myv invention arc specially adapted vfor batteries of the. lead type. I have found that daring thel op-y eration of Ibatteries of this type, tine neelle-like crystals of metallic lead form .on thenegative plates, and that when separators having perpendicular apertures are used, some of these needlesv will grow 'through the apertures until they'touch the positive plates thus '.fotining a short circuit. By my present invention I providea separator which has no perpendicular apertures, and which, therefore, prevents all short circu'iting by means of these vineedle--lihe crystas`..'

In the accompanying drawings I 'haveV show-n a .separator embodying invention,

`and forA purposes of illustration, I have shown abattery with the separators in place. I desirejit to be understood, however,l that I do not limit myself to the exact forni of batterj,T which` IV have shown, lor to the exact -forinl of separator. vVarious changes in structural details may be made within the scope of my invention. i

In the drawin,gs- Figurel l is a cross see tional view of ay storage battery having-sepa! rators embodying my` invention. Fig. 2- is a side elevation of a separator. Fig. B is a cross sectional view along the line 3&3 of

Fig. 2, and lig. fi is a fragmentary edge elevation.

Referring to the drawings, l representsthe storage battery jar which may be of any suitable material such as hard rubber, or glass. u

2, 2 represent the posit-ive plates of the battery, and they may formed of iead, and

able active material. 2 are connected to the terminal 3.

. hard. rubber; may be the interstices thereof tilted with any suit-l The positive. plates Q,

.4l-etere the negative plates which may benlso formed of lead. llhese are connectedto'the terminale Y'lctween each positivo u I l and negative plate is located a separator e, to be hereafter fully Vldescribed. The 4-jar is filled with a suitable electrolytewhich surrounds ',th-e plates andestablishes electrical connection between them. i

The' separator comprises two .series 4of parallel, vertical,"equally spaced str-ips 7,. the strips of each series being in the saine plane with one another and parallel to the` plane of the other series. .The strips ofthe two series are off-set relative'to 4one another and overlap asshown inF-ig.-

Between th overlapping' 'portions of the strips are. fornied connecting portions 8. These "connectingportions are 'separated froml one ani other to 'forni the horizontal apertures 9, It will' beseen that by this construction', ll. have providedl communication between the two sides of the separator, but'have pro- C vided no perpendicular open-ing from one side tov the other, and have, therefore, inade it impossible for any crystalline growth,

such as abovedescribed, to forin a short circuit between the plates.'

rEhe separator may be bniltnp. of separate parts, as above describei1 if desired, or it may be formedi'n one ii.. l piece. "I pre fer tolforinI the parator ol wood, but any other usual or preferred material, such as used.
